The basic principle of Ultra-Low Temp. Water-Cooled Chiller is that under ultra-low temperature, the movement of molecules is slowed down until the surface of the trapped and frozen cryogenic coiled tubes is slowed down, and the vapor is easy to be arrested, set and frozen, and the capture rate is high.
LNEYA specializes in the production of single-fluid cryogenic chillers. The refrigeration temperature ranges from -150°C to -5°C, which can meet the needs of different refrigeration temperatures. Products are widely used in chemical, pharmaceutical, biochemical and other industries in the field of low temperature reaction, refrigeration speed, safety and reliability. The company developed a direct-cooled ultra-low temperature chiller, using international brand compressors Carrier, using automatic cascade refrigeration mode and mixed refrigerants, within 3 minutes can be refrigerated to minus 120°C.
1.Temperature ranges from -5℃ ~ -150℃, can meet different temperature
2. Famous brand semi-closed piston compressor, semi-closed bipolar piston compressor, semi-hermetic screw compressor, main brand are BOCK. Bitzer, Copeland, Handbell, fusheng; Plate heat exchanger, Small volume, High efficiency
3. Top imported cold controller; Generator cooling water circuit uses intermediate heat exchanger, improve system reliability and safety.
4. DANFOSS electronic expansion valve, high precision control;
5. Adopt Siemens PLC S7-200/300, LNEYA touch screen, automatic control, temperature curve display, temperature record U disk, fault alarm;
6. Offer machine installation and system test, users only need to finish the installation of refrigerant and cooling water.
